17 meter delta loop antenna

Strapped for space and looking for a compact 17 meter antenna?  Build yourself a 17 meter delta loop.  It will fit in a space 13′ high, 2′ wide, and 20′ long.  The lower radiator (3) is only 1′ above ground.  Referring to Figure-1 below, the antenna is fed at the junction of radiators (2) and (3) with a 4:1 current balun connected to 50 ohm coax transmission line. Approximately 60′ of #14 AWG stranded THHN coated wire, (2) insulators, guy ring, single 15’+ non-metallic mast,  SO-239 connector block, rope, and (2) stakes are all you need to make the antenna.

I have made 17 meter SSB phone contacts around the U. S. (AZ, CA, NY, FL) and most recently with Vrhnika, Slovenia using the antenna with a ICOM-706MkIIG running 100 watts.  My QTH is in Cary, NC.

SAFETY NOTE:   High voltages can be present on portions of the antenna when transmitting.  If you are operating in the field with the antenna, erect a warning sign and use orange colored tape to surround the area around the antenna.
